General Motors has announced the official power ratings for the 6.2L V8 engine that powers the 2014 Chevrolet Silverado and the 2014 GMC Sierra – numbers that make the new top of the line GM half ton pickups the most powerful available on the market today.

The new 6.2L V8 that powers the 2014 Chevrolet Silverado 1500 and the 2014 GMC Sierra 1500 offers 420 horsepower and 460lb-ft of torque. An output of 420 horsepower makes the 2014 Silverado and Sierra the most powerful trucks sold in America. Not the most powerful half ton trucks – the most powerful trucks, period. For comparison, the highest horsepower truck available from Chrysler’s Ram brand is the 2014 Ram HD with the new 6.4L Hemi which offers 410hp. The most powerful truck from Ford Motor Company (again, in terms of horsepower) are those F150 pickups fitted with their 6.2L V8 that puts out 411hp.

More importantly, the new 6.2L GM V8 truck engine available in the 2014 Chevy Silverado and GMC Sierra offers more torque than any other gasoline-powered pickup available in the US market. While the heavy hitting and high priced diesel engine options in the Ford Super Duty and Ram HD offer substantially more torque than the new 6.2L GM gasoline motor, the new Chevy and GMC trucks pack more torque than any other non-diesel truck sold in America. In a segment where many buyers focus more on torque than horsepower, the fact that GM offers the highest torque output of any gasoline engine in America should be a major selling point for the company.

“Power and towing capacity are fundamental capabilities for full-size pickups,” said Jeff Luke, General Motors Executive Chief Engineer for full- and mid-size trucks. “The 2014 Silverado and Sierra deliver unmatched power and towing capability with a host of ingenious driver aids.”

GM hasn’t provided full information on the 2014 Silverado and Sierra towing numbers but the company’s statement announcing the segment leading power output mentioned that a properly equipped Silverado or Sierra 1500 will offer a towing capacity of 11,500 pounds when fitted with the 5.3L V8 and those trucks powered by the 6.2L engine will tow an impressive 12,000 pounds. Those maximum towing capacities make the new Chevy and GMC half ton trucks the leader in the class as the Ram 1500 has a towing capacity of 10,450 pounds and the Ford F150 will pull a best of 11,300 pounds. As mentioned, details are very limited but the GM statement does point out that the max towing package that will allow the 2014 Silverado and Sierra to pull 11,500 pounds will rely on the smaller 5.3L V8 with “only” 355 horsepower and 383lb-ft of torque and this will not be available until later this year. It is also unclear whether the 6.2L towing capacity of 12,000 pounds also requires a similar max towing package but that doesn’t make all that much of a difference as even the “lower line” 5.3L V8 offers a better towing capacity than any other half ton truck on the market.
